Not too sure of weblogic console but i havent come across any such utility in the other application server's console, i doubt if you will find one. Logically a console is used to deploy an application and not generate one to be deployed.
However if you find this Command prompt approach to be tedious you can use
ant to build your app.
If you still want one simpler approach specific to your
test projects, why not have a bat file prepared to build the war file.
